This is safe to change breaking the ABI because ...

Names are supposed to be local to the module, not based on their source.

The driver was only just merged so didn't make it into a full
release.

yes. DTS changes are still in review state.

Okay. Will take care next time. As external MCLK is supported from both 
modules, audio cc and core cc,

for now it's mandatory to change the name to avoid confusion.
